Dusseldorf, Germany, a Corporation of Germany I Application September 6, 1927, Serial No. 217,847, and in Germany January 3, 1927 1 Claim.

Applications have been filed in Germany, January 3, 1927, January 6 1927 and April 25 1927.

This invention relates to improvements in or modifications of the means for separating adhering rolled metal sheets as described in the specification of,my prior U. S. application for patent Ser. No. 159,735 filed 7th January, 1927, which has become Patent No. 1,749,075, and essentially consisting in splitting the adhering rolled metal sheets open at their front ends and pulling the same freely over a cutterlike contrivance engaging between them and having a separating motion during the'free travel of the sheets over the same.

According to the present invention, means are provided for increasing the separating action of the cutter-like contrivance. To this end, the latter is moved to and fro in the plane lying between the sheets to be separated, in a manner depending on the adhering resistance to be overcome, the thickness and width of the sheets to be separated, and the strength of the latter.

The cutterlike separating contrivance can, for instance, be reciprocated in said plane in a direction parallel to the pulling direction of the sheets. Said contrivance is preferably provided with a sawlike cutting-edge and reciprocated in said plane in a direction transversely to the pulling direction of the sheets. Or, it can consist or two superposed parts having each a sawlike cutting-edge and which are reciprocated in said plane in opposite directions transversely to the pulling direction of the sheets. In all cases, a compressed-air motor can be coupled directly with the cutterlike'contrivance for driving the same and imparting thereto a high speed of at least 200 units of movement per minute, for, obviously, the separating action ofthe cutterlike contrivance is increased with increasing speed of the same. Furthermore, means are provided for guiding the cutterlike contrivance during its rapid reciprocation.

The accompanying drawing illustrates diagrammatically by way of example how the in- I vention can be put into practice:

Fig. 1 is a side view partly in section, while Fig. 2 is a fragmentary plan view, of a. practical constructional form of the improved apparatus, and Fig. 3 is a front view of the apparatus.

Figs. 4 and 5 are respectively a plan view and a front view of a modified construction of the cutterlike contrivance with its guiding and drivmg means.

Referring to Figs. 1- and 2The sheets to be separated are caught by the tongs 2 and pulled by means of the cords 3, drum 4, toothed-gearing 5, and motor 6, over the cutterlike separating contrivance 1. i

In Fig. 2 it is seen that thecutterlike contrivance 1 is provided with a sawlike cuttingedge, the tongs 2 and pulling cords 3 being shown behind the same. The cutterlike contrivance is rapidly reciprocated in the plane of cleavage between the sheets and in a direction transversely to the pulling direction of the sheets, by means of the motor 7, bevel-gearing 9, shaft 8 and eccentric 10 with which the cutterlike contrivance is connected.

Figs. 4 and 5 show atwo-part cutting device having a sawlike cutting-edge on each of its two superposed cutting members 11, 12 which are mounted in lateral guides 13 and in direct connection with compressed-air motors 14, 15 by which they are rapidly reciprocated or oscillated generally along their axes in the plane of cleavage between the sheets and in relatively opposite directions transversely to the pulling direction of the sheets. I

What I claim, is:-

Apparatus for separating adhering rolled sheets including the combination, with means for positively moving a pair of adhering sheets in a feeding direction, of a pair of superposed cutting devices provided with sawlike cutting edges, which cutting devices are disposed transversely between said sheets and individually reciprocable while in mutual contact and along their own longitudinal axes in the cleavage zone transversely to the direction of movement of said sheets, and means for individually reciprocating said cutting devices in said cleavage zone in opposite directions in order to add a direct splitting action to the cutting action of said cutting devices while generally maintaining thenormal fiat shape of said sheetsas uniformly as possible during separation thereof.
